8. Changeling
In Irish folklore, a changeling is a fairy child left in place of a human infant, often resulting in a sickly or altered child. This belief mirrors similar tales in German and Slavic cultures, where fairies or trolls are said to abduct human children, leaving behind a changeling. Such myths reflect societal fears and the mysteries surrounding unexplained illnesses or developmental differences in children (irelandsmythsandlegends.com).
